Because organisms that became index fossils lived only during specific intervals of geologic time, geologists can estimate the ages of rock layers based on the particular index fossils they contain.

Why are index fossils more useful then other fossils to paleontologist?
It is because the index fossils has better minds than the paleontologist.
What fossils are useful in determining the relative age of rocks?
Index fossils
Why are index fossils are more useful to paleontologists than many other fossils?
im trying to figure that out myself
Why are index fossils useful for figure out the age of a set of disturbed rock layers?
index fossils are useful for figuring out the age of a set of disturbed rock layers by index fossils are used to determine when rock layers were formed so if they were used to figure out the age of a set of disturbed rock layers than they can also figure out when they were formed .
Why are the Eurypterids in these cross sections not useful as index fossils?
The Eurypterids in these cross sections not useful as index fossil because they are only found in certain areas are a long lived organism
Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
Would horseshoe crabs be useful as index fossils?
No because they have been alive for a very long time
How are index fossils useful to geologist?
Index fossils provide a reference of time throughout rock layers. In order to be a good index fossil, the life form must have lived for a short and specific amount of time and must have existed over a large area. Index fossils serve as a reference to geologists in correlating rock layers. They can match up (or correlate) the index fossils which helps them match up (or correlate) the rock layers.
Fossil used to compare the relative ages of fossils?
index fossils
What are index fossils and how are they used to determine the absolute age of sedimentary rock?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.

How can fossils be used to date the rock in the strata?
Because index fossils are useful because they tell the relative ages of the rock layers in which they occur. They also tell what year they were made.
